Dam pumping station data supervisory system

1.1 PCAuto data acquisition subsystem

1.1.1 functions outlines

The PCAuto data acquisition subsystem establishes in the dam pumping station inspection station, undertakes main river course 口门 dam pumping station accent water movement correlation information gathering, will gather the data message storage will stand in each floodgate in the real-time monitor service storehouse, then further will store through the DBCOM module in the integrated service storehouse. The inspection station not only may in the automatic gathering correlation dam pumping station accent water information, but also the passable integrated service storehouse has carried on the dispatch information with other subsystems interactive, guaranteed other subsystems may real-time obtain the dam pumping station the state of the water information, the equipment movement information, the river course floodgate stand the basic information and so on.

1.1.2 gathering main information
?nbsp;inside and outside river water level
?nbsp;rainfall
?nbsp;the strobe opens
?nbsp;floodgate current capacity
?nbsp;water pump switch
?nbsp;water pump current capacity
?nbsp;river course water quality
?nbsp;equipment failure signal
1.1.3 data acquisitions subsystem characteristic
?nbsp;security
In operation strict jurisdiction management. The system should provide the audit trail function, the recording all users operating process, to the system security problem which appears provides the investigation the basis and the method; The system should have business diary function.
?nbsp;timeliness
Real-time gathering information and so on in scene state of the water, labor sentiment, rainfall situation, and its existence service database in. Has a stronger timeliness and the higher processing efficiency, must be short to the visit response time; Gathering connection timeliness is good, can satisfy its application the need; The gathering connection gathering cycle (may according to need to carry on hypothesis) in 5 seconds to 5 minutes between; Gathering connection timeliness cannot affect the industrial control system the performance.
?nbsp;use
Operation contact surface simple, is easy to understand; The system maintenance convenience is quick; Two developments connections must standardize; The disaster sex breakdown restoration must simple, be reliable.
?nbsp;fault-tolerant, redundancy
The gathering connection is having the condition situation, the realization redundancy; Gathers software to have to have the fault-tolerant processing mechanism; The real-time database system has the fault-tolerant ability, according to concrete hardware condition realization redundancy.
?nbsp;先进?br> Establishes open, the standard, may expand, is easy manage, the promotion real-time database system. Not merely must achieve advanced which disposes, what is main develops and in application advanced.
?nbsp;uses the flowmeter in the system carries on the survey to the floodgate current capacity and the water pump current capacity, has provided the essential condition for the network of waterways water power water quality model movement and the implementation.
?nbsp;many kinds of reports to the police the way: May report to the police, the handset short note through the acousto-optics reports to the police Germany only then and so on to report to the police the way to carry on to the water level ultra higher information reports to the police.
1.1.4 realizations functions
?nbsp;to gathers the information by the tendency way the real time display
The gathering parameter like floodgate station floodgate position animation (by procedure drawing way) the conformable display, the real-time monitoring data which the real-time gain floodgate stands, and based on data and so on gain floodgate position, water level, current capacity, rainfall, selects the method which the animation (strobe frontage, side) simulates, direct-viewing reflected the floodgate stands current condition. Strobe simulation chart two side writing prompt, rod (inside and outside river water level, current capacity)
 
?nbsp;real-time data curve
The real-time reflection gathering information change, facilitates to gathers the information the analysis and the inquiry; Forms the floodgate station, the region water level, the current capacity and so on the real-time graph curve.
?nbsp;historical data time interval curve (parameter and so on water level, current capacity)
May recall a belt millisecond label the data, the convenient accident inquires ; May form historical graph trend curve and so on floodgate station, region water level, current capacity.
?nbsp;reports to the police the information
Automatic recording system mode change, operating process and so on important event. Once has the accident, may take in light of this the analysis accident cause factor the basis, recalls for the realization accident, provides the basic data.
The system may provide Gao Bao, the high newspaper, the low newspaper, the low low newspaper, the deviation, the rate of change, the time delay, bad PV, the input overtime reports to the police the function, provides reports to the police the confirmation, reports to the police compiles, reports to the police function and so on historical inquiry.
Reports to the police, the lower limit regarding the low lower limit reports to the police, high limits reports to the police, the altitude limit reports to the police, when when the process value has surpassed the limiting value which these four kinds reports to the police, produces corresponding reporting to the police.
Reports to the police regarding the deviation, when the process value (PV) with supposes the definite value (SP) when the deviation has surpassed deviation limiting value DEV, reports to the police the production.
The rate of change reports to the police is through the examination process value (PV) actual rate of change, namely if the process PV value has surpassed rate of change limiting value RATE after the change cycle RATECYC change quantity, produces reports to the police.
The bad real-time observed value reports to the police examines whether has the bad real-time observed value to report to the police the value appearance.
?nbsp;data report form
Regarding data which gathers including floodgate figure according to, water level data, current capacity data, rainfall data and so on, forms the data report form; The report form has following several kinds:
1) historical report form
The historical report form can carry on the daily paper, the monthly report, the quarterly report, the annual report production, the logarithm according to the memory time scope, the gap, the outset time may carry on wilfully assigns, and may act according to the time which saves to carry on the inquiry history data.
2) multi-purpose report form
May wilfully establish the report form form, realizes each kind of operation, the data conversion, the statistical analysis, the report form printing and so on. Also may manufacture the real-time report form, also may manufacture the historical report form. May in the report form simultaneously demonstrate the real-time data and the free time historical data, and performs to count processing, for example takes the good average, the row average, counts the biggest minimum value.
1.1.5 data acquisitions and control device
The system uses the data acquisition and the control device use Schneider PLC Mcro37, this equipment and between the data acquisition subsystem carries on the connection through Unitelway, real-time gathering parameter and so on scene water level, rainfall.
1.1.6 subsystems analysis situses chart

According to this in new window browsing picture
1.1.7 systems distributed situations
Has a PCAuto real-time data server in the dam pumping station, the scene real-time data completes gathering through PLC, simultaneously supposes as soon as monitors the terminal, the realization all data acquisition system all monitors function. In the control center, supposes a server and a monitoring terminal, the database server saves in all real-time databases through the network the data message and other correlation information, through monitors the terminal to be allowed 内监 to measure the dam pumping station scene in the control room the real-time situation.
